This is a handy bundle of 6 items to get you started right away in the world of Arduino. The bundle includes: Arduino Uno R3 (DIP Version), 400 hole breadboard, jumper wires, breadboard and Arduino holder, USB cable and 9V battery connector.The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter.Technical Specifications:Microcontroller: ATmega328Operating Voltage: 5VInput Voltage (recommended): 7-12VInput Voltage (limits): 6-20VDigital I/O Pins: 14 (of which 6 provide PWM output)Analog Input Pins: 6DC Current per I/O Pin: 40 mADC Current for 3.3V Pin: 50 mAFlash Memory: 32 KB (ATmega328) of which 0.5 KB used by bootloaderSRAM: 2 KB (ATmega328)EEPROM: 1 KB (ATmega328)Clock Speed: 16 MHz
